The behavior of the human body in extreme physical activity is of great interest to various spheres of human activity. In order to perform their duties, the people working in such conditions (e.g., astronauts, pilots and rescuers) must be in good physical training. The athlete’s body adapts to systematic high (sometimes close to the limit) exercise, in connection with which changes and its physiology. Continue reading
Overtraining is a physiological condition in which there is a violation of the fitness of the human body after a regular physical stress. Overtraining is accompanied by the appearance of fatigue and decreased ability to perform physical exercise. What are the disorders on the physiological level are evolving state of overtraining? What are the consequences of the consequences of such conditions and whether they can lead to poor health? How to provide for the body’s recovery from overtraining?
Overtraining occurs most frequently in a systematic and excessive pace training in sports and fitness clubs in those who had not previously received such exercise. In people who have not yet adapted to the increased motor activity in sports, recovery after intense workouts cannot provide full replenish energy in the body and maintain the health of muscle fibers. When this physiological condition is violated, the activity of the whole organism. Particularly vulnerable to such danger nervous and cardiovascular systems.
There are several varieties of overtraining. Continue reading
In our publications about the Chinese gymnastics and health practices of different types, we decided to start with the basics – breathing exercises. This is one of the fundamentals of harmony, longevity and a healthy lifestyle. And one of the foundations of success of Chinese ancient and modern medicine and such global economic projects, such as the Chinese society and the Chinese economy.
From the beginning on the website Zdravo-Bravo was said about the importance in our lives proper breathing. And then, finally, you, our dear readers, start to receive valuable information about practices breathing exercises qigong. And other health technologies.
We already told you about qigong in General and its tracks, now begin to print preparatory articles, more specific information about Chinese medicine. and specific information about the practical exercises from the field of how the movement and breathing exercises. In order not too often be repeated in the words,we introduce to you the term “tens of Hz”, “tens of Hz”, or “DC,” which would mean “breathing exercises qigong”, or simply “breathing exercises”.

People involved in fitness because I want to be beautiful and healthy. And not only in the result but in the process of doing exercises. The latter contributes a very comfortable outfit.
A type of sportswear served as underwear. In the 70-ies of the last century in Germany were first fans of Jogging in city parks. The most acceptable (from the point of view of convenience or to public morality) clothing was wool knitted underpants and Spodnja shirt. However, painted in a darker color. After the first world war tracksuit acquired some charm: narrow sweater with collared Golf and a wide flannelette bloomers
began to sheathe decorative elements in the form of stripes and emblems.
But the bathing suit, by contrast, has evolved from complex to simple. Lush dress, especially made for swimming, gradually (and very slowly) shortened, decreased the number of frills and ruffles. In the early twentieth century was some sort of scandal with Australian swimmer Continue reading
How to learn to swim. Why it is useful swimming. Swimming for weight loss. Techniques and styles of swimming
To learn how to swim is helpful. The benefits of swimming for health. The main styles of swimming.
Swimming is the ability to move on water and under water due to the movements of his own body. The ability to swim has the most living organisms on the planet, including man. However, unlike walking and running in humans have not developed the automatic ability to swim. As in cats, dogs or even more aquatic animals. Swimming requires the formation of a complex motor reflexes . In this respect, this physical activity like riding a bike, rollerblading, running on jumpers, etc. to Teach swimming
and can infants and especially adults. During swimming training activated by a bark of the big hemispheres of a brain.
The concept of functional systems was mainly based on the study of motor behavior reactions. According to P. K. Anokhin, starting stimulus activity of an organism is the physical factor, which acts on the background of the situational afferentation during the synthesis process in the higher parts of the brain interfaced with congenital and acquired experience (memory) and the dominant motivation. On this basis there is a choice of one or more directed paths functioning of the body, called the decision an
The adopted program with the target unit (the acceptor of result of action) via efferent pathways delivers the Executive signal which actuates the working devices: occur muscle contraction,secretion of glands, etc. and Then from the relevant receptors in the acceptor of the action comes reverse afferentation message about the result of the act. If the latter does not reach the target fixture installation, then the reaction is repeated or adaptation is another way. Continue reading
Engaging in leisure activities, people strive to maintain and improve your health, increase efficiency, improve health, get a boost of optimism and good mood. But often, instead of tidal energy and pleasant emotions after a workout man haunted by muscle pain, cramps, feeling of weakness. The main reason for coming to physical exhaustion and accumulation of chronic fatigue is the inability to draw up a workout program. In addition, many lose sight of that for a quick recovery after the load is not less important proper rest.
Why you need a recovery period
During the sport becomes more active metabolism, which leads to an increase in the rate of oxygen consumption and energy, the rise in body temperature. As a result in the muscle tissue there is a deficiency of nutrients, and accumulate oxidized products, lamivudina in the blood and causetoxicity. This enhances the feeling of fatigue, weakness. Of particular significance is lactic acid. in high concentrations causing pain and twitching of individual muscle fibers. To compensate for the infringement, immediately increases the frequency and volume of respiration, blood flow velocity, increased sweating. But for full recovery after a workout the body needs about 3 days. Continue reading
Load and rest as interrelated components of the process of exercise: the “external” and “internal” side of the load, volume and intensity as part of the load, recreation
Load – the impact of physical exercise on the human body, causing a strong reaction from its functional systems (V. N. Platonov, 1987).
Load – the number of exercises performed, the time spent on classes and other indicators. The load – response of the body to work.
For most physical exercise in their total load on the body adequately characterized by the following components (V. M. Zatsiorsky, 1966):
Intensity – the magnitude and direction of the impact of physical exercise on the human body (speed, pace). Changes in the intensity of exercise has a direct impact Continue reading
It is known that regular physical activity and sports practice many organs and systems of the human body, which, of course, improves health and improves health.
The movement is a very important component of health. It stimulates many processes in the body. Child couldn’t grow into a full adult human if he did not commit such a huge amount of different movements.
In our body contains about 65% of liters of liquid, and it must be continuously circulated, so that the cells received all necessary materials, and waste is removed. The liver, kidneys, lungs, skin and intestines must be healthy and clean in time to eliminate the toxins.
The multiple increase circulation of fluids in the bodycontributes to the movement: running, walking, exercise. When we move, our muscles contract, the liquid is extruded into the blood stream, and venous blood moves to the heart.
Thanks to increased blood circulation and respiration, are emitted from the body the toxins of fatigue, resulting in the impact on human performance. Continue reading
The published material is infringing? please let us know.
The concept of “physical activity” shows the obvious fact that any of the exercises connected with the transition energy of the body functioning at a higher than at rest, level.
If you take the amount of energy in the supine position “1”, then a slow
walk at a speed of 3 km/h will increase the metabolism in 3 times, and running with acropetally speed and similar exercises in 10 and more times.
Thus, the exercise requires a higher, relative to its rest position power consumption. The difference that occurs in energy consumption between the state of motor activity (e.g. walking, running) and the rest refers to the physical Continue reading
